摘      要：Morphing technology is one of the most effective methods to improve the flight efficiency of *** control surfaces based morphing method is mature and widely used on current civil and military aircraft,but insufficiently effective for the entire flight *** research on morphing wing still faces the challenge that the skin material for morphing should be both deformable and *** this study,a continuous morphing trailing-edge wing with a new multi-stable nano skin material fabricated using surface mechanical attrition treatment technology was proposed and *** fluid dynamics simulation was used to study the aerodynamic performance of the continuous morphing trailing-edge *** show that the lift coefficient increases with the increase of deflection angle and so does the lift-drag ratio at a small angle of *** importantly,compared with the wing using flaps,the continuous morphing trailing-edge wing can reduce drag during the morphing process and its overall aerodynamic performance is improved at a large angle of attack *** field analysis reveals that the continuous morphing method can delay flow separation in some situations.
